摘要: 以甘肃省陇东黄土董志塬为研究区,采用SWAT模型和遥感方法,就黄土台塬区地下水库均衡进行综合研究. 结果表明:黄土台塬区土壤水分负均衡常出现在5、6月份,该期水分亏缺不利于植被的健康稳定生长,是灌溉调节的主要时段. 1981-2010年间,气温升高使陆表蒸散需求增加,降水减少使土壤水库补给减少,二者共同导致台塬区土壤水库负衡态势的加重. 气候变化背景下,积极寻求外调水源是解决黄土台塬区水资源短缺问题的重要手段.

Abstract: In this study, the hydrologic model of SWAT and the remote sensing methods were combined to illustrate the dynamics of the soil water reservoir in the loess tableland. The Dongzhi Loess Tableland was selected as a study area to comprehensively and quantitatively determine the water balance of the soil water reservoir. It is found that a distinct monthly variation of water in the soil water reservoir and a soil water deficit takes place frequently in May and June, which restricts land surface ecology. Irrigation regulation ought to be especially considered in the two months. During the period from 1981 to 2010, increase of air temperature and decrease of precipitation had led to more evaporative and less recharge to the soil water reservoir, respectively. Both result in more negative water balance of the soil water reservoir in the area. It is verified that under the background of climate change, an overall plan for external water transfer into the area must be considered and implemented as soon as possible to deal with the water shortage problem.

Key words: soil water reservoir, equilibrium, loess tableland
